Grivel Rambo IV

The Rambo IV is the latest generation of Grivel's most technical crampon, integrating an active anti-balling plate and simplifying all adjustments: just one screw to adjust the length, just one screw to substitute a point, just one screw to position the spur.
A rigid crampon with anatomic curve, asymmetrical forged mono-point, extremely easy to substitute with just one screw, integrated with a half point external lateral support point: a new solution for external support.

Structure in rigid plastic acts as a spacer for the screws and as support for the supple rubber anti-balling device.
The accordeon in supple rubber holds together the front and rear parts of the anti balling system.
Four retention points for descent. Moveable spur.
